SS5U100PA 产品概述 — 扬杰 (YANGJIE)

SS5U100PA 是扬杰半导体推出的一款高压肖特基整流二极管,属功率级 Schottky Barrier 二极管,封装为 TO-277 形式,适用于要求低正向压降、快速恢复和高温工作的功率整流场合。该器件在中等电流级(直流正向电流 5A)和 100V 反向耐压下,结合较小的正向压降和抗浪涌能力,常用于开关电源、整流及保护电路。

一、主要电气参数一览

  • 型号:SS5U100PA
  • 品牌:YANGJIE(扬杰)
  • 封装:TO-277(功率型散热片可固定的穿孔/插件封装)
  • 直流正向电流(If): 5A
  • 正向压降(Vf):0.8 V @ 5 A
  • 直流反向耐压(Vr):100 V
  • 反向漏电流(Ir):100 μA @ 100 V
  • 非重复峰值浪涌电流(Ifsm):200 A
  • 工作结温范围:-55 ℃ ~ +175 ℃

二、关键特性与优势

  • 低正向压降:0.8V(在 5A 条件下)能显著降低导通损耗,提升整流效率,尤其在高频开关电源或高电流回路中可减少发热和能耗。
  • 快速恢复与肖特基特性:肖特基结构本身不存在显著的存储电荷,开关损耗小,适合高频电源应用。
  • 中等电流与高浪涌承受能力:5A 连续、200A 单次浪涌能力,使其可承受启动或故障瞬态电流冲击。
  • 宽温域工作:-55~175 ℃ 的结温范围提高了在严苛环境(如工业、汽车周边)中的可靠性余量。
  • 高压等级:100V 的反向耐压适合 48V 及以下电源系统中的整流与保护应用。

三、典型应用场景

  • 开关电源整流(输出二极管或快速整流)
  • DC-DC 转换器的续流/回授保护二极管
  • 反向极性保护与电源路径控制(如电池管理、UPS)
  • 太阳能逆变器或电池充放电回路中作为防反接或整流元件
  • 工业电源、马达驱动电源的保护与整流场合

四、热管理与电路布局建议

  • 封装为 TO-277,通常带有金属散热片或固定孔,建议在高功率场合使用适当尺寸的散热器或将器件紧固于金属底座以增强散热。
  • 在 PCB 上给予器件引脚足够的铜面积或铺设散热填充层(大面积铜箔、若干热过孔)以降低结温。
  • 正向压降随温度可能略有下降,但反向漏电流随温度显著上升;在高温环境下应适当降额使用或增加散热措施。
  • 浪涌电流(Ifsm)为非重复峰值,不能作为重复冲击条件下的长期工作参考;需配合熔断器或软起动电路限制冲击能量。

五、选型注意事项

  • 若工作电流常驻高于数安培且对效率敏感,SS5U100PA 的 0.8V Vf 为良好选择;若需更低 Vf(例如在 10A 等更高电流档位),可考虑更大规格或并联多只器件,但并联时需注意电流共享与散热设计。
  • 当系统电压接近或超过器件 Vr(100V)上限时,应留有裕量;例如在 48V 系统中考虑过压瞬态(雷击、开关瞬变),需要额外的浪涌抑制与稳压保护。
  • 如果应用场合对反向漏电流非常敏感(例如高阻抗测量、低功耗待机),反向漏电 100 μA 可能需被替代为漏电更小的型号或加并联抑制电路。

六、可靠性与工艺建议

  • 建议遵循厂商推荐的回流焊温度曲线和散热紧固扭矩,避免因过高的机械应力或温升导致封装/焊点失效。
  • 在长期高温或频繁浪涌环境下,应做热循环与冲击评估,确认结温、封装与焊接的可靠性。
  • 设计时预留结温监测或热保护机制(如温度传感器、过温关断),以延长器件寿命并保证系统安全。

总结:SS5U100PA 是一款面向中等功率整流与保护的肖特基二极管,凭借 0.8V 的正向压降、100V 的耐压能力以及良好的浪涌承受能力,适用于多种工业与电源应用。选择时应重视散热与反向漏电随温度上升的特性,结合系统电压、电流与热场分布做合理的设计与降额。若需更详细的引脚、热阻或封装尺寸信息,请参照扬杰官方数据手册或联系供应商获取完整版规格书。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
